We show that the space symmetry of bilayer systems, coupled by both tunneling and Coulomb interaction, has fundamental influences on the collective charge-density excitations. In the general case of two-subband occupation, three modes with one intersubband and two (optical and acoustic, respectively) intrasubband plasmons are calculated. By breaking the space symmetry, these modes are found to be ...
